[Diagnosis and treatment of adhesive intestinal obstruction in children].

The work analyses 455 patients with acute adhesive intestinal obstruction (194 children with the early and 261 with the advanced stage of the disease). The most common causes of the obstruction were acute appendicitis, developmental anomalies of the intestine, and intestinal intussusception. Complete viscerolysis and horizontal intestinoplication by means of medical glue without application of sutures were performed in a total adhesion process, even in the acute period (34 cases). Severe paresis or paralysis of the gastrointestinal tract is an indication for its decompression. Laparoscopy was conducted in 90 children (from 3 months to 14 years of age) in suspected acute adhesive intestinal obstruction. The diagnosis was confirmed or defined more exactly in 64 patients. As the result of endoscopic operations intestinal obstruction was corrected and laparotomy was avoided in almost half of the patients. The total mortality was 1.3%.

[Isolation of the bronchi with intraoperative packing in children with bronchiectasis].

The authors discuss experience in 168 operations for extirpation and segmental resection of affected bronchi in children with bronchiectases. To prevent recanalization of the bronchus after its segmental resection and to prevent the formation of an abscess in the isolated part of the lung they suggest a method for intraoperative packing of the remaining bronchi with biopolymer material.

[Use of heterogenous materials in the surgical treatment of fecal incontinence in children].

Operations were carried out on 40 male and female patients with stage III incontinence of feces from 1970 and through 1980. Their ages ranged from 8 to 14 years. The disease was caused by unsuccessful correction of anorectal developmental anomalies. The following operations were performed: after Wreden on 16 patient, after Faerman on 12, after Makhov on 8 and after Thiersch on 4 patients. The follow-up periods ranged from 2 to 6 years. A recurrence was found in all of the children. Y-shaped sphincteroplasty and a modified Wreden's operation with the use of heterogeneous material have been developed and introduced into practice in the clinic since 1983. Twenty two patients with stage III incontinence of feces were operated on, the result was positive in the majority of cases.

[Diagnostic and therapeutic tactics in various forms of cholangiopathies in children].

Seventy children with obstructive cholangopathy were examined in the clinic in the recent 15 years: 48 children had "cholangiopathy of the newborn" and 22 had a cyst of the common bile duct. A total of 44 operations were carried out: on 22 infants with cholangiopathy of the newborn and on 22 with cysts of the common bile duct. The most informative methods for the diagnosis of cholangiopathy in children are as follows: ultrasonic scanning, laparoscopy, ERCPG, aspiration biopsy of the liver, and aspiration cholangiography under control of a laparoscope. Kasai's operation is the operation of choice in obstructive cholangiopathy of the newborn. The operation of choice in cysts of the common bile duct is cystectomy with choledocho- or hepaticojejunostomy on an isolated loop after Roux.

[Formation of antireflux small-to-large intestinal anastomoses in resection of the ileocecal angle].

The results of the resection of the ileocecal angle and creation of the different types of small-to-large intestinal anastomoses in 52 children at the age of from 5 mos to 14 yrs were analysed. The authors have developed in the experiment and employed in 9 children the modification of the invagination anastomosis according to Ya. D. Vitebsky with the use of a silicone tube. This permitted to reduce the incidence of postoperative complications.

[Surgical treatment of urethral strictures in children].

Under analysis were results of treatment of posttraumatic strictures of the urethra in 34 children. A method of treatment of the urethra structures has been developed in experiments in dogs with the use of permanent magnet. Comparison of results of treatment of 2 groups of patients treated by traditional methods (19 patients) and by the proposed method (15 patients) has shown that using the new method is followed by two times less amount of recurrences and complications.

[Inflammatory diseases of the greater omentum in children].

The authors' experience with the treatment of 46 patients with secondary and primary omentitis is presented. Operations were performed in all the children. Resection of the altered portion of the omentum was fulfilled in primary omentitis. Draining operations were performed in cases with secondary omentitis. It was found that primary omentitis was caused by a hematogenic infection of peripheral portions of the greater omentum, the secondary omentitis being due to a residual inflammatory process in the resected omentum stump or not correct assessment of its state and rejection of resection while performing appendectomy.

[Preoperative diagnosis of Hirschsprung disease in children].

Twenty children of different age suspected of Hirschsprung's disease were examined. The complex examination included contrast irrigography, electromyography and determination of tissue acetylcholinesterase. The reliable diagnosis was established in 10 children. The distal border of agangliosis was found and thus the methods of treatment could be chosen.
